This is the western climb up Teide, starting from the outskirts of Chio, just follow the TF-38 all the way up to Mirador de Boca Tauce. It's one of the shortest ways up to the top and slightly easier. It's a steady gradient with lots of straight sections on the road. Road surface is excellent with little traffic. Just admire the uniqueness of El Teide. Make sure you have enough water and food for the climb.
